Product Description

The SN74HC74QDRG4Q1 is part of the 74HC series, known for its high-speed Si-gate CMOS technology. This technology ensures low power consumption while maintaining high switching speeds. The device is designed to operate from a wide range of supply voltages, from 2 V to 6 V, making it flexible for various power environments.

Each flip-flop has independent data, set, reset, and clock inputs, and Q and Q-bar outputs. The set and reset inputs are asynchronous, allowing for immediate setting or resetting of the flip-flop, which is useful for initialization or emergency shutdown procedures. The positive-edge-triggered clock input, on the other hand, allows for synchronized state changes across the system.

With its wide operating temperature range, the SN74HC74QDRG4Q1 is suitable for automotive applications, including engine control units, infotainment systems, and advanced driver-assistance systems (ADAS). The device's robustness is further ensured by its compliance with the AEC-Q100 automotive qualification standard, signifying its reliability under harsh conditions.

Manufactured in a compact SOIC-14 package, the SN74HC74QDRG4Q1 is designed for space-constrained applications, providing essential functionality without compromising performance. Its surface-mount design allows for efficient assembly in printed circuit boards, contributing to modern, streamlined electronic designs.
